Artifact-free computed tomography of the chest and abdomen in the severely ill patient.

A method is described for obtaining consistently high-quality images during nonneurologic computed tomography of the severely ill and uncooperative patient using a neuromuscular blocker to induce apnea. Careful control of respiration during data acquisition eliminates motion artifacts.

An approach to mid-facial fractures.

The purpose of this article is to present a concept which facilitates the plain film identification of mid-face fractures. The concept evolves from a logical classification of mid-face fractures based upon the region(s) of involvement (orbit, zygoma, maxilla), the extent of the fractures (unilateral or bilateral) and the characteristic distribution of the fracture lines. Recognition of these fractures depends upon an awareness of the fact that the radiographic signs of mid-face fractures differ in certain respects from those involving other skeletal parts.

High-dose computed tomography in the evaluation of low attenuation lesions in the neck.

Recent reports have established the clinical utility of computed tomography (CT) in the evaluation of jugular vein thrombosis. Other abnormalities of the soft tissues in the neck can mimic this condition. This study reviews the pertinent normal soft tissue and vascular anatomy of the neck and describes the use of high-dose CT in the evaluation of low attenuation lesions in this area.

Gallbladder enhancement following angiography: a normal CT finding.

The authors reviewed computed tomography (CT) studies that had been preceded within 2 days by angiography. Twenty-one patients were selected who showed no laboratory evidence of liver or renal disease. Eighteen patients received greater than 37 g of iodine at angiography.
